A stent or other intraluminal medical device having markers formed from housings integral with the stent and marker inserts having a higher radiopacity than the stent provides for more precise placement and post-procedural visualization in a vessel, by increasing the radiopacity of the stent under X-ray fluoroscopy. The static model is a rigorous predictive model that is trained over a wide range of data, whereas the dynamic model is trained over a narrow range of data. Simplified models, besides their application to multi-resolution rendering, can provide clues to the shape of the input object. The movable units are each equipped with an electrical battery for smoothing the load from the movable unit on the primary side of the transfer system. The invention is characterized in that a pivotable projection device is provided and constructed in such a way that a variable size projection display and means for detecting the position andor the movement thereof are obtainable. or a mixture of at least two active ingredients each having a melting point of <80\xb0 C.
